Abstract
The utility model relates to a manhole cover and a well base made of composite materials. The base is in the shape of an inversed trapezoid with a rectangular circular ring, and a rectangular position is provided with a reinforcing rib. The outer diameter of the manhole cover is matched with the inner diameter of a supporting wall of the annular well base, and the manhole cover and the well base are both made of mixed composite materials of waste and old plastics and pulverized coal ash. The manhole cover of the utility model has the advantages of heavy weight, favorable dimensional stability, no turn via impact and high safety.
Description
Technical field
The utility model belongs to the design of composite material well lid and seat.
Background technology
At present, the well lid of all kinds of manholes and well seat are mainly cast iron, steel part, steel concrete and woodwork etc.The casting iron well lid anti-seismic performance, dynamically load-carrying properties are bad, and steel well lid corrosion resistance is poor, and the concrete manhole cover weatherability is bad, can not be subjected to heavy duty for a long time, and insulation well and safety factor that wooden well lid can only be used to not have under the heavily loaded situation is low.Chinese patent ZL93233407.5 " the road surface manhole cover of belt washer ", Chinese patent ZL93216580.X " anti-stealing manhole cover " etc., it is under the relatively poor situation of environment that these well lids exist unavoidable problem, the hinge place is dead by rust easily, the very effort that drives a well sometimes for situation in the instant manhole, is had to well lid smashed and is reinstalled, and the Manhole cover with lock complex structure, the cost height.
Summary of the invention
The purpose of this utility model is a kind of composite material well lid of design and seat.
This well seat is trapezoidal for garden, right angle ring, and has designed reinforcing rib at the place, right angle, and the external diameter of well lid and ring-type well seat supports wall internal diameter match, and well lid, well seat all use waste or used plastics and flyash blended compound material to make.
The utility model does not add any inner lining steel skeleton, makes intensity lasting.Because iron and steel differing greatly with the plastic hot coefficient of expansion, both cementabilities are poor, cause when environment temperature is low, iron and steel shrinkage ratio plastics are fast, easy and the plastics generation space of iron and steel liner skeleton, form internal flaw, the stress when stressed near the subrange of defective sharply increases, and the goods bulk strength reduces.In the higher time of environment temperature, iron and steel expansion ratio plastics are fast, form stress concentration easily, easily produce stress cracking, will seriously reduce the intensity of material.
The specific embodiment
The technical solution of the utility model is described below in conjunction with the accompanying drawings:
Accompanying drawing 1 is the schematic diagram of composite material well lid and seat
Fall among the figure trapezoidal cylinder well lid (1) external diameter with fall trapezoidal ring-type Jing Zuozhichengbi (3) internal diameter and match, have open hole (2) on the well lid, ring-type Jing Zuozhichengbi (3) is perpendicular with annulus platform (5), is provided with reinforcing rib (4) at the place, right angle.
The utility model well lid is heavier and dimensional stability good, is hit and does not renovate, and is safe and reliable.
Claims (1)
1. composite material well lid and seat, it is characterized in that down that the external diameter of trapezoidal cylinder well lid (1) and trapezoidal ring-type Jing Zuozhichengbi (3) internal diameter that falls match, have open hole (2) on the well lid, ring-type Jing Zuozhichengbi (3) is perpendicular with annulus platform (5), is provided with reinforcing rib (4) at the place, right angle.
